This new technology, I think this is a very, very well-designed heart. It's got this maglev technology. So the disc is rotating, sort of freely floating and rotating by this magnetic levitation like you'd use for the trains, you know, the floating trains in Japan. It doesn't have valves. It's got really clever systems because your heart has to pump through your body.

It has a very strong left ventricle to do that and a lighter ventricle to go through your lungs. And that has to happen together with every beat. And they've managed to do it.
